While loaded as shown in the DEEP DRILLER Sample Load Form #3 (Preparing to Drill), all of the casing is discharged. What is the change in LCG?

Correct Answer: Option B — -0.45 foot

Longitudinal Center of Gravity (LCG) calculations for sample load forms involve moments and weights. Discharging casing removes weight forward or aft of the initial center, producing a shift of -0.45 foot as verified by stability booklet procedures.
